[Product Description]

Based on zirconium salt, an amorphous nano-ceramic coating was deposited on a clean metal surface by a new composite technology. The adhesion between metal and coating is improved, and the corrosion resistance of coating is enhanced.

[Performance Characteristics]

1, Green environmental protection. No phosphate, no heavy metals, no sediment cleaning, simple wastewater treatment.

2. Outstanding benefits. Room temperature (no heating required), short reaction time (15 ~ 200s), no need to do closed treatment, low new line construction cost.

3. Excellent performance. Strong coating adhesion, excellent reprocessing performance, coating neutral salt spray test (NSS), better than iron phosphating, boiling water for 2 hours, 100 cells adhesion level 0, fast impact deformation test, no falling off, bending test, no falling off.

[Product Usage]

chemicals

Ceramicizing agent ZP-525 adjuster ZP-300

Groove configuration:

Slot concentration: 2 ~ 5% Slot pH range: 4.0 ~ 5.5

For every 1000kg of tank liquid: when adding ZP-525 is 20-30kg, if the pH of the tank is lower than 4.0, a small amount of ZP-300 should be added while stirring to control the final pH in the range of 4.0 ~ 5.5

Control points:

pH value: 4.0 ~ 5.5 Concentration: 2% ~ 5%

Time: 30 ~ 120S (spray) 90 ~ 240S (soak)

Temperature: room temperature

Film weight

The total film weight of the conversion film is 30 ~ 130 mg/m2 and the zirconium content of the film is 15 ~ 65 mg/m2
